Die Fotografie – ein neues Bildmedium im Wissenschaftspanorama des 19. Jahrhunderts. Einführung in das Symposium

Photography – a novel medium of scientific representation in the XIXth century array of arts and sciences. To delve into various nineteenth century academic disciplines under the heading ‘photography in the arts and sciences’ as did last year's annual conference of the History of Science Society – the interest in such a topic only partly stems from the ‘iconic turn’ that has generally enlarged the scope of the social sciences in recent years. A more poignant feature in any such present day study will probably be a basic scepticism facing the fact that in public use photographs have been manipulated in many respects. Yet, while shying away from any simple success story, a historically minded approach to changing ‘visual paradigms’ (Historische Bildwissenschaft) has begun to emerge. In this context, it has proved of considerable heuristic value to reconsider the role of early photography in an array of science, arts and technology: Since the reliance on the traditional ways of sketching reality persisted, in many an instance where photography was introduced, the thoughts the pioneer photographers had about their new, seemingly automated business, call for close attention. Thus scholarship sets up a parallel ‘discussion room’; the lively debate on the benefit of academic drawings as opposed to photographic portraits is a case in point. Some fairly specialised reports on photographically based analyses, such as electron microscopy, point to a borderline where the very idea of representation as a correspondence of reality and imagination gets blurred. Even though any ‘visual culture’ will have to shoulder the ‘burden of representation’, it is equally likely that it will offer a deeper sensibility for the intricacies entailed in the variegated ways of illustrating or mapping chosen subjects of scientific interest. Scholarship may thus somewhat control the disillusionment that by now has become the epitome of writing on photographic history. Provided with a renewed methodological awareness for the perception process and its photographic transition, historians may strike a better balance between the ever present tendencies of a realistic and an aesthetic way of picturing the world we live in.     

Fotografie als Wissenschaft

Photography as Science: In 1908 the English physicist Arthur Mason Worthington published A Study of Splashes, a treatise on the physical behaviour of falling drops. The photographic experiments were performed by means of an electric spark „in absolute darkness”︁. Worthington's experimental practice dealt with two different areas of knowledge production: an area the operator could perceive control from the outside and a corresponding black-box where the photographic recording itself took place. The paper discusses the epistemic challenges of this specific shift from imperceptible events to their photographic representations. It shows to what extent the information revealed by the photographic apparatus had to be converted, for it did not speak for itself. Thus, Worthington's work went beyond the classical dichotomy between objectivity and imagination.     

Outer form and internal disease: clinical photography in the late 19th century

Clinical photography in the late 19th century aimed at unveiling the hidden processes invisible to the clinical eye. Changes in the outer form hinted at deeper lying causes, and decoding these forms was supposed to extend the range of the clinical eye in to the realm of invisibility. Two suppositions supported this hope: the belief that each disease as an ontological entity showed typical exterior signs which allowed a diagnosis at sight, and the technological trust in photography as a precise and objective means of representation superior to the human eye. For a short time, clinical photography seemed to be the 'via regia" of diagnosis. Heinrich Curschmann's Klinische Abbildungen and Ludwig Jankau's periodical Internationale medizinisch-photographische Monatsschrift marked the climax of this development in Germany. R?ntgen's discovery and its immediate application in clinical medicine put an end to the optimistic expectations: clinical photography was from now on only one among many different means of documenting clinical signs and findings.     

Visualisierungen in der deutschen Geographie des 19. Jahrhunderts. Die Beispiele Robert Schlagintweit und Hans Meyer

Visualization in 19^th‐century German geography: Robert Schlagintweit and Hans Meyer as examples. – Visual representations of nature formed an essential part of 19^th‐century earth sciences. In particular, colonial photography – as a visual source, and as an instrument of the construction of national identities – serves essential research interests of current history and social sciences. The present paper is a case study on the role and function of photography in German geography of the 19^th and early 20^th centuries. It focuses on the work of the Munich geographer Robert Schlagintweit (1833–1885) and the Leipzig colonial geographer Hans Meyer (1858–1929); the early history of photography in India and the function of images in the geographical exploration of overseas territories are discussed. Although there is nearly half a century between the work of R. Schlagintweit and H. Meyer, their photography shows remarkable parallels. The ideas of both on the practice of visualization are rooted in pedagogic and didactic concepts as well as in popular science. For both geographers photography was essentially a technical help, which often needed graphic revisions. And they both preferred photography to depict people and buildings (compared, for instance, to landscapes). Concerning the more comprehensive question of how far their photography transmitted a specific German ‘image of abroad’, it is indicated that such a specific image should have its essential roots in a peculiar visual culture of German earth sciences in the first half of the 19^th century. Thus the paper offers a starting point for further studies discussing the change from a ‘Biedermeier image’ of foreign cultures to a more ‘colonial’ one in 19^th‐century German geography.
